Claims (7)

  1. Le rotor de l'éolienne à axe de rotation vertical, possédant au moins deux supports horizontaux liés au moyeu, aux extrémités desquels les pales du rotor sont fixées et calées d'une manière rigide dans la zone du centre de leur hauteur aux extrémités des supports, à la fois chaque pale du rotor est composée de deux ailes liées entre elles, où la coupe transversale de ces ailes constitue une lame symétrique ou convexe concave, et à la fois la longueur de la corde ainsi que l'épaisseur de la lame diminuent en s'approchant des extrémités de l'aile, caractéristique par le fait que l'aile supérieure (3a) et l'aile inférieure (3b) du pale du rotor (3) s'écartent de manière radiale de la zone du centre vers l'extérieur (3c) en formant l'angle de déviation (β1, β2) par rapport à l'axe de rotation du rotor, et à la fois la longueur de la corde (b2) de la lame aux deux extrémités de l'aile (3a, 3b) ainsi que la longueur de la corde (b1) dans la zone du centre (3c) sont à peu près inversement proportionnelles aux rayons (R1, R2) de leur position par rapport à l'axe de rotation du rotor.
  2. Le rotor selon la revendication 1 caractéristique par le fait que l'angle de déviation (β2) de l'aile inférieure (3b) dépasse l'angle de déviation (β1) de l'aile supérieure (3a).
  3. Le rotor selon la revendication 2 caractéristique par le fait que l'angle de déviation (β2) de l'aile inférieure (3b) dépasse de 1° à 5° l'angle de déviation (β1) de l'aile supérieure (3a).
  4. Le rotor selon la revendication 1 ou 2 caractéristique par le fait que la longueur (l2) de l'aile inférieure (3b) dépasse la longueur (l1) de l'aile supérieure (3a).
  5. Le rotor selon la revendication 4 caractéristique par le fait que la longueur (l2) de l'aile inférieure (3b) dépasse d'environ 2% jusqu'à 15% la longueur (l1) de l'aile supérieure (3 a).
  6. Le rotor selon la revendication 1 caractéristique par le fait que les supports (2) possèdent une lame symétrique avec une corde disposée horizontalement et l'axe oblongue des supports passe par le centre géométrique des lames et croise l'axe de rotation du rotor.
  7. Le rotor selon une revendication des revendications de 1 à 6 caractéristique par le fait que les pales du rotor (3) sont liées aux supports (2), en utilisant les points connus de l'angle d'incidence (y) sur l'angle critique d'incidence (y) qui permet d'effectuer les changements d'une étendue de -2° à +3°.
